Answers

Answer 1
Answer:

Answer: D. They act to break down the protective barriers around the egg, allowing the sperm.

Explanation:

Acrosin and other protease enzymes functions by the catalyzing the proteolysis, that is the breakdown of proteins into small polypeptides by cleaving the peptide bonds within the proteins by the process of hydrolysis.

The acrosine and other protease enzymes are released by the acrosome cap of the spermatozoa. This process facilitates the enzymatic digestion of zona pellucida layer of the egg. This helps in the penetration of egg by the sperm.

The cell that does not have a cell wall is the _____.

Answers

Answer:

Animal cell that does not have a cell wall.

Explanation:

  • An animal cell does not have a cell wall because they do need the cell wall.
  • The cell wall is present in plant cells, its function is to maintain the shape of the cell.
  • The function of the cell wall is to provide shape and structural support to the cell, it made up of cellulose.
  • If the cell wall is present in the animal then it will become stiff, and would not able to carry their usual work. So they lack a cell wall.

Thus the animal cell does not have a cell wall.
The plant cell has a cell wall; The animal cell is the cell without the wall. So it would be animal

The question refers to various stress reduction techniques which have been shown in research to have numerous benefits for both physical and psychological health. These techniques include exercise (both short and long duration), social support networks, and interventions involving positive psychology.

Explanation:

The subject of the question is referring to various stress reduction techniques. Research has shown that these techniques provide numerous benefits for both physical and psychological health. These techniques cover a wide array, including exercise, social support networks, and positive psychology tactics.

Exercise, both of long and short duration, has been proven to be beneficial for physical and mental health (Salmon, 2001). It is found that physically fit individuals are more resistant to the adverse effects of stress and recover more quickly.

Social support networks too have favorable impacts on health outcomes. They offer several beneficial physiological effects in stressful situations and lead to better health behaviors.

Lastly, interventions involving positive psychology, such as documenting three good things that happened each day, also led to an enduring increase in happiness and reduced stress (Seligman et al., 2005).

Mental health therapies often utilize a combination of these techniques to enhance the psychological and physical well-being of individuals.
